This is otherwise a pretty interesting article. But I'm befuddled by the passage highlighted below. I honestly can't tell whether this is meant to say that "interest groups" made up a disease entity where none really existed, or whether "interest groups" successfully fought for recognition of a disease in the face of those who denied its existence. And what 'interest groups' are meant - patient advocacy groups? http://www.nejm.org/doi/full/10.1056/NEJMp1113569 The Burden of Disease and the Changing Task of Medicine David S.

Well, yeah. And God forbid they should.
